| | | | | | | | | | | | | | | | | | | | The model types are not part of the core QML runtime and should only be loaded if you explicitly import them.

* | V4: Change both setter0 lookup methods to reflect getter0Erik Verbruggen2019-03-011-8/+8
|/ | | | | | | | | | | | | | The setter0Inline would do the index to offset calculation each time it was called, while getter0Inline would do it once when creating the lookup. Same for setter0Memberdata. Both setters now mirror the behavior of their getter counterparts. However, getterTwoClasses is more sophisticated than setterTwoClasses, so there we still use the existing setter0setter0, but restore the uncorrected index back into the two-class-lookup.
